Prompt

Create a UiPath Flow project named "SubflowDemo" that takes a string input
called "text" and reverses it. The string reversal logic should be
encapsulated inside a subflow rather than done directly in the main flow.
Return the reversed string as an output.

Do NOT run flow debug — just validate the flow.
Do NOT ask for approval, confirmation, or feedback. Do NOT pause between planning and implementation. Build the complete flow end-to-end in a single pass.
Before starting, load the uipath-maestro-flow skill. Read and follow its workflow steps exactly.

## ✅ SubflowDemo Flow — Complete

**File path:** `SubflowDemo/SubflowDemo/SubflowDemo.flow`

### What was built

**Main flow (3 nodes, 2 edges):**
| Node | Type | Role |
|------|------|------|
| `start` | `core.trigger.manual` | Entry point; surfaces `text` as flow input |
| `reverseSubflow` | `core.subflow` | Calls the reversal subflow, passing `text` as input |
| `end` | `core.control.end` | Maps `reversedText` output from `$vars.reverseSubflow.output.
